The pump barrel is equipped with an outer pipe, which is threaded at the upper end and suspended at the lower end. The outer pipe bears the tensile force generated by hanging the tail pipe, anchoring the oil pipe anchor, and setting the sealing packer, which can improve the stress condition of the pump barrel, prevent the bending deformation and pump jamming phenomenon of the pump barrel. Simple structure, reliable operation, deep pump hanging, convenient operation, suitable for deep wells.
